METAL CUTTER.

Application filed November 17,1925, Serial No. 69,654, and in canadaluly 30,1925.

The present invention pertains to a novel.

knife of the cutter. To this'bar is pivoted l he movable knife which co-operates with the fixed knife. A double bearing is provided with a pair of branches lying at opposite sides of the knives and connected by transverse members passing through the body beneath the longitudinal bar. In these branches is pivoted a follower which engages the movable knife, and the pressure thereon is exerted against the transverse members which in turn bear against the longitudinal bar. For this reason, the bar is firmly see cured tothe body by such devices as are deemed suitable. V

In order that the follower may be effectively actuated by hand, a lever is pivoted L toone end of the longitudinal'bar and linked to the follower. An extension handle is provided with the lever so that the leverage may be varied if desired. A jig strap is supported at one side of the body forv holding the work, and a gauge is mounted at the other side of the body in order to measure the length of the piece to be cut;

The invention is fully disclosed in the fol lowing description and in the accompanying drawings in which;

Figure 1 is a side elevation of the device;

Figure 2 is a plan view thereof;

Figure 3 is an elevation of the movable knife;

Figure 4 is a bottom plan view thereof;

Figure 5 is a longitudinal section of the device;

Figure 6 is a transverse vertical section; and

Figure 7 is a front elevation.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

The device comprises a body or block 1 which rests upon a suitable base 2. On the block is laid a longitudinal bar 3 engaged at one end by a strap 4 having bolts 5 passed through the ends thereof and secured to the base 2 as shown in Figures 1, 5 and 7.

Through the forward end of the bar 3 is passed a bolt 6which also passes through the body 1 and isheld in a recess 75 in the bottom of the body by a plate 8. Over the rear end of the bar is passed a U-bolt 9 which extends to a recess 10 in the bottom. of the body and is there held by a clamp plate 11 secured to the ends thereof.

The bar 3 serves to support the block 12- of the lower or fixed knife, the blade 13 of which is secured tot-he-backas illustrated inFigure 6.- The bar has a cavity 14 in which oneend of the back 15 of the movable knife is pivoted. To'the lower edge of the back is secured a knife block 16' by means of screws 17 as shown in Figure 3. This block has a dovetail socket 18 in which the movable knife blade 19 is' fixed; The fixed blade 13 is held to its block 12 in the same manner.,

The doubl'ebearing member consisting of like branches 20 and 21 disposed at opposite sides of the bar 3 is mounted upon the body 1. This double bearing is an integral structure, the branches being held together by transverse members 22 which. pass through the body 1 beneath the bar 3 as-s-hown in Figure 5. Reinforcing metal plates 23- are secured alongthe lateralwall'softhe body 1' near the upper'edgethereof and-by-thef'eet of the hearing: The plates are clamped against the-body by b'olts'2 t passing-throughthe body. At one side of, the-body, the bolts also-hold a pair of angle pieces 25-having each-as-lot' 26in the outer'end. A 'i'gstraip- 27 has its ends placed over these slots and secured in this position by a bolt 28 passed through these ends and through the slots, the bolt being tightened by a wing nut 29.

Between the branches 20 and 21 of the bearing member is pivoted a follower 30 which is curved downwardly and held in engagement with the back 15 by a yoke consisting of straps 31 secured to the ends of the back and a bolt 32 passed through the straps and lying over the follower. The rear end of the bar 3 is formed with a bearing 32 in which is pivoted an operating lever 33. The lever is connected to the free end of the follower 30 by means of a link 34 pivoted to both these members. The lever carries a pair of straps 35 in which a handle 36 may be adjustably fitted in order to vary the leverage.

In the use of the device, the work is passed beneath the strap 27 and over the lower blade 13. In the body is supported a measur ing rod 37 projecting outwardly and carrying an adjustable gauge 38. After the gauge has been set, one end of the work may be brought against in order to measure a length of the piece to be out.

While a specific embodiment of the inven tion has been illustrated and described, it is to be understood that various alterations in the details of construction may be made without: departing from the spirit of the invention as indicated by the appended claims.

Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent is l. A metal cutter comprising a body, a longitudinal bar lying on said body, a fixed knife secured to said bar, a movable knife pivoted to said bar, an upright bearing mounted in the body, a follower pivoted in said bearing and slidably engaging said movable knife, a lever pivoted to one end of the bar, and a yoke secured to the fixed knife and receiving said follower.

2. A metal cutter comprising a body, a longitudinal bar lying on said body, a fixed knife secured to said bar, a movable knife pivoted to said bar, an upright bearing mounted in the body, a follower pivoted in said bearing and engaging said movable knife, a jig strap supported at one side of the body, and a gauge provided at the other side of the body.

8. A metal cutter comprising a body, a longitudinal bar lying on said body, a fixed knife secured to said bar, a movable knife pivoted to said bar, an upright bearing mounted in the body, a follower pivoted in said bearing and engaging said movable knife, a lever pivoted to one end of the bar, a link connection between said lever and follower, a jig strap supported at one slde of the body, and a gauge provided at the other side of the body.

J r metal cutter comprising a body, a longitudinal bar lying on said body, a fixed knife secured to said bar, a movable knife pivoted to said bar, a double bearing having branches disposed at opposite sides of said knives, transverse members passing through said body and connecting said branches, a follower pivoted between said branches and slidably engaging said movable knife, a lever pivoted to one end of the bar, and a yoke secured to the fixed knife and receiving said follower.

A metal cutter comprising a body, a longitudinal bar lying on said body, a fixed knife secured to said bar, a movable knife pivoted to said bar, a double bearing having branches disposed at opposite sides of said knives, transverse members passing through said body and connecting said branches, a follower pivoted between said branches and adapted to engage said movable knife, a jig strap supported at one side of the body, and a gauge provided at the other side of the body.

6. A metal cutter comprising a body, a longitudinal bar lying on said body, a fixed knife secured to said bar, a movable knife pivoted to said bar, a double bearing having branches disposed at opposite sides of said knives, transverse members passing through said body and connecting said branches, a follower pivoted between said branches and adapted to engage said movable knife, a lever pivoted to one end of the bar, a link connection between said lever and follower, a jig strap supported at one side of the body, and a gauge provided at the other side of the body.

In witness whereof I have hereunto set my hand.
